Description
Technical field
The present invention relates to glass processing device fields, more particularly to a kind of glass tempering fuel Heating of indirect heating
Furnace.
Background technique
Existing glass tempering heating furnace usually heats glass using the heat that stratie issues.Example
Such as, notification number is the Chinese invention patent of CN2265979Y, discloses " a kind of rotary heating furnace for bending toughened glass ", passes through
The resistance wire inside round heating furnace is mounted on to heat glass.It is such in such a way that resistance wire radiations heat energy heats
There is defects, and since glass blackness is small, reflectivity and transmissivity is relatively high, and absorptivity is lower, based on radiant heat transfer
Heating method is wanted, the problems such as there are heating time is long, low efficiency.In addition, a large amount of electric energy can be consumed using Resistant heating glass,
It causes the production cost of tempered glass technique larger, influences the market competitiveness.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of glass tempering fuel oil heatings of indirect heating, by high temperature
Gas injection is to refractory ceramics plate surface, heating ceramic plate, then by radiation, indirect heating glass surface realizes glass temperature
Degree increases.
The technical solution adopted by the present invention to solve the technical problems is：A kind of glass tempering fuel oil of indirect heating is provided
Heating furnace, including furnace body and glass roller-way, the inner horizontal of the furnace body are equipped with glass roller-way, the both ends of the glass roller-way
Corresponding with the glass at furnace body both ends inlet and outlet, being internally located above and below glass roller-way for furnace body is mounted on
Refractory ceramics plate, the surface of the refractory ceramics plate are provided with first coating, are arranged on four wall of furnace interior
There is second coating, burner noz(zle), the burner noz(zle) and fuel passage phase are mounted at the top and bottom of the furnace body
Even.
One kind that the first coating and second coating is all made of Low Temperature Thermal plasma spray coating can absorb numerous spectrum
Energy and the ceramic powdery stratum granulosum that can unify to emit near infrared spectrum.
As a supplement to the technical solution of the present invention, the burner noz(zle) is flat flame burner.
Further, the top and bottom of the furnace body are at least mounted side by side there are two burner noz(zle).
Fuel oil enters upper and lower nozzle by pipeline and burns, and flame is sprayed by nozzle, the pottery of heating addition specific coatings
Porcelain plate, glass of the ceramic wafer in a manner of radiant heat transfer on heated table, glass absorb the heat radiated from four wall of furnace body, thus
Complete the heating process in glass tempering process.
Beneficial effect：The present invention relates to a kind of glass tempering fuel oil heating of indirect heating, heating furnace is made by fuel oil
So that burner noz(zle) is sprayed high-temperature gas to ceramic wafer upper surface for fuel, glass is then heated by the indirec radiation of refractory ceramics plate
Glass, selected ceramic wafer can emit the wavelength in particular range, i.e., the wavelength absorbed most beneficial for glass, this is just effectively solved
The defects of traditional heating furnace of having determined existing heating efficiency when heating glass is low and heating time is long.In addition, using fuel oil and
It is not that the heating method of resistance wire can also substantially reduce production cost, glass can also be made using ceramic wafer indirect heating glass
Surface is heated evenly, and is solved traditional heating furnace due to heating the problems such as unevenly causing glass defect, is protected glass quality
Card.It is 3.2-5.0 μm based on the optimal wavelength range that glass can be absorbed, portion is realized with addition coating process in heating furnace
The ray for emitting the wavelength can be shortened heating time, improve production efficiency.
